How many kinds of electric belt are there, how are the models classified
The profile of the trapezoid synchronous belt with the trapezoidal band is a single surface with two kinds of teeth. It is short for single and double-sided. Double-sided tape again in tooth arrangement is divided into symmetric teeth type code (DA) and staggered tooth type (code DB). Trapezoidal tooth synchronous system with two kinds of size: pitch system and modular system. Using pitch system in our country, and according to the ISO 5296 to formulate the corresponding synchronous belt transmission standard GB/T 11361-11362-11361 and GB/T 11616-1989.
Arc tooth synchronous belt arc tooth synchronous belt besides tooth profile for curved shape, the structure and basic same trapezoidal tooth synchronous belt, belt pitch, the depth of tooth, tooth root thickness and fillet radius are larger than the trapezoidal tooth. After the loading of the teeth, the stress distribution is better, and the stress concentration of the root of the tooth is smooth, and the bearing capacity of the tooth is improved. Therefore, the synchronous belt of arc teeth is more powerful than the trapezoidal synchronous belt, and prevents the interference of teeth in the mating process. The arc tooth synchronous belt is good for wear-resisting, the noise is small at work, not lubrication, can be used in the bad environment of dust. It has been widely used in food, automobile, textile, pharmaceutical, printing and paper industry.
Classification of synchronous belt The synchronous belt has a trapezoidal tooth and a curved tooth. There are three kinds of arc teeth: the arc tooth (the H series, also known as the HTD band), the flat top circular teeth (the S series, also known as the STPD belt) and the concave top parabolic teeth (R series).
